Abstract
Articles are made from a stable mix containing an aqueous dispersion of rubber, fillers, vulcanizing-agents, &c. and at least 0,5 per cent free alkali by rendering the mix unstable and pouring it into a mould before thickening begins, setting, removing the article from the mould, washing, and drying under conditions that allow the contained water to escape. Preferably the dispersion has a solid content of at least 70 per cent and the stable mix a content of 60 per cent solids. With unconcentrated latex, thickeners, such as gum kayara, or sodium salicylate may be added to prevent fillers from settling. As setting agents, ammonium chloride, nitrate, carbonate, and acetate are specified, preferably used in combination with other substances such as zinc salts. Zinc oleate may be used alone. Alkali earth metal salts, and acetic acid may also be used. Quick setting is desirable and may be brought about by the use of a quick-setting agent, a large quantity of setting agent, or by heating the moulds. A mixture of magnesium oxide, sodium triphosphate, and ammonium chloride sets the mix quickly in the cold. According to an example, 1300 gm. "Revertex," 150 gm. zinc carbonate, 30 gm. sulphur, 10 gm. zinc diethyldithiocarbamate, and 415 ccm. water are mixed with 230 ccm. of a 30 per cent solution of ammonium nitrate, and poured into a mould heated to 80-90 DEG C. For cold setting, 380 ccm. of a 71 per cent solution should be used. The set article is removed from the mould, and washed for 3-4 hours, and is then slowly dried, at a temperature rising to 40 DEG C. It is then vulcanized at 70-85 DEG C. The process is suitable for the manufacture of soles and heels, bathing and other shoes, balls, tiles, mats and the like. In making soles and heels, metal washers may be placed in the moulds, and the mix poured round them. Specifications 284,608, 292,964, 326,210, and 330,536, [all in Class 70, Indiarubber &c.], are referred to.
